Physicists use a 350-year-old theorem that explains the workings of pendulums and planets to reveal new properties of light waves. Since the 17th century, when Isaac Newton and Christiaan Huygens ...

Planck's constant reveals the quantum world's fundamental energy levels. It shows how light and matter exist in discrete units (quanta). This constant defines limits to our knowledge of particle ...

Brand new data from CERN indicates a particle that moves faster than the speed of light. If this really were the case, it would be almost unbelievable news that breaks with everything that physicists ...
